Cell Theory, Structure,and Function Flashcard

Front

What is the Cell Theory?

Back

The Cell Theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

Front

What type of cells are plant and animal cells?

What is the function of the cell membrane?

Back

The cell membrane is a semi-permeable layer that encloses the contents of the cell and regulates the movement of substances in and out of the cell.

Front

Which structures are found in both eukaryotic and prokaryotic cells?

Back

Ribosomes.

Front

What invention in the 17th century contributed to the development of modern cell theory?

Back

The light microscope.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the function of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What is a cell wall and which cells have it?

Back

A cell wall is a rigid outer layer that provides support and protection; it is found in plant cells, fungi, and some prokaryotes.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy (ATP) through cellular respiration.
